Not a hotrod...but does anyone know where the cabin air filter is on a 2004 Chevy Tahoe? All information I find says passenger side under dash. I have pulled the decorative cover off the A/C case, remove the passenger kick panel, and the glove box. I cannot see anything that will remove to expose the air filter.

I just went to wixfilters.com because I know they have location codes.
They don't list one for a Tahoe, but they do for the GMC Yukon.

Wix PN for the Yukon (with the 4.8 engine only) is 24814, with a location code of "3", which translates to "behind glove compartment"

I also had a look at Autozone. They do list a "CAF1812P" cabin air filter (which also crosses to that Wix 24814), but the page crashes when you ask for the related repair guide.???

Just for fun, I thought perhaps they might mention (or show a picture) in with the blower motor replacement instructions. They don't ... but it looks like there were 2 different systems used in that truck. Visteon and Delphi.
This makes me speculate that perhaps only one of these systems uses a cabin air filter?
The repair gude was also a bit "generic", and applied to the following models:
Escalade, Suburban, Tahoe, Yukon, Denali, DenaliXL, YukonXL 1999-2005

NAPA Pro-link also listed the same filter (NAPA / Wix #4814), but again ... only for the Yukon.

Yes, the 1812P is the filter I got. The AutoZone site just says passenger side under dash . There is a flat area the thickness of the filter where it looks like it would fit, but no way to get it open short of splitting the condenser case . I guess mine is the one you mentioned that does not use a cabin air filter. Thanks for the information none the less

the filter if euipped is between the fan motor and distribution box. if you look under the glove box, almost riht in front of you is a 1 inche wide vertical plastic strip held in by old screw under neath.behind there is a paper filter. very few have this option and if yours doesn't, you should be very happy.
